java - 无法将 spring.example.service.UsuarioService 字段 spring.example.config.security.SecurityConfig.usuario 设置为 $Proxy47

Question

当我运行网络应用程序时，我遇到此错误:

SEVERE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private spring.example.service.UsuarioService spring.example.config.security.SecurityConfig.usuario; nested exception is java.lang.IllegalArgumentException: Can not set spring.example.service.UsuarioService field spring.example.config.security.SecurityConfig.usuario to $Proxy47

我猜这与此配置类的 Autowiring 属性有关:

@Configuration
@ComponentScan(value="spring.example")
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UsuarioService usuario;

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .userDetailsService(usuario)
            .passwordEncoder(encoder());
    }

    private Md5PasswordEncoder encoder() {
        return new Md5PasswordEncoder();
    }

    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
                .disable()
            .authorizeRequests()
                .antMatchers("/acesso/erro").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/acesso/login").permitAll()
                .loginProcessingUrl("/login").permitAll()
                .usernameParameter("login")
                .passwordParameter("senha")
                .defaultSuccessUrl("/acesso/start")
                .failureUrl("/acesso/login")
                .and()
            .rememberMe()
                .key("lembrete")
                .useSecureCookie(true)
                .and()
            .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/acesso/login").permitAll();
    }

}

我的类 UsuarioService.java 有这个实现:

@Service
public class UsuarioService implements UserDetailsService {

    private UsuarioDao usuario;

    @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
    public UserDetails loadUserByUsername(String arg0) throws UsernameNotFoundException {
        Usuario account = usuario.findByField("login", arg0);

        if(account==null) {
            throw new UsernameNotFoundException("No such user: " + arg0);
        } else if (account.getAutorizacao().isEmpty()) {
            throw new UsernameNotFoundException("User " + arg0 + " has no authorities");
                    }

        boolean accountIsEnabled = true;
        boolean accountNonExpired = true;
        boolean credentialsNonExpired = true;
        boolean accountNonLocked = true;

        return new User(account.getLogin(), account.getSenha(), accountIsEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(account.getAutorizacao()));

    }

    public List<String> getRolesAsList(List<Autorizacao> list) {
        List <String> rolesAsList = new ArrayList<String>();
        for(Autorizacao role : list){
            rolesAsList.add(role.getNome());
        }
        return rolesAsList;
    }

    public static List<GrantedAuthority> getGrantedAuthorities(List<String> roles) {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        for (String role : roles) {
            authorities.add(new SimpleGrantedAuthority(role));
        }
        return authorities;
    }

    public Collection<? extends GrantedAuthority> getAuthorities(List<Autorizacao> list) {
        List<GrantedAuthority> authList = getGrantedAuthorities(getRolesAsList(list));
        return authList;
    }

}

什么可以为我指明正确的方向？我认为还有另一种方法可以在我的 SecurityConfig 类中使用此 Service 类，但我可以发现我的代码与网络上其他可用的代码之间的任何差异。

Answer 1

您正在 SpringConfig 中 Autowiring 具体类 (UsuarioService)，而不是接口(interface) (UserDetailsS​​ervice)。看看 answer here 中的第 2) 点.

您应该在配置中像这样 Autowiring UserDetailsS​​ervice:

@Autowired
private UserDetailsService usuario;
